The invention provides a fuel oil composition F) comprising F1) a fuel oil of mineral origin and F2) a fuel oil of vegetable and/or animal origin, and, as a cold additive, the constituents A) at least one copolymer composed of ethylene and 8-21 mol% of at least one acrylic or vinyl ester having a C1-C18-alkyl radical and B) at least one comb polymer containing structural units composed of B1) at least one olefin as monomer 1 which bears at least one C8-C18 alkyl radical on the olefinic double bond, and B2) at least one ethylenically unsaturated dicarboxylic acid as monomer 2 which bears at least one C8-C16 alkyl radical bonded via an amide and/or imide moiety, where the sum Q (see above formula) of the molar averages of the carbon chain length distributions in the alkyl radicals of monomer 1 on the one hand and the alkyl radicals of the amide and/or imide groups of monomer 2 on the other is from 21.0 to 28.0, where w1 is the molar proportion of the individual chain lengths in the alkyl radicals of monomer 1, w2 is the molar proportion of the individual chain lengths in the alkyl radicals of the amide and/or imide groups of monomer 2, n1 are the individual chain lengths in the alkyl radicals of monomer 1, n2 are the individual chain lengths in the alkyl radical of the amide and/or imide groups of monomer 2, i is the serial variable for the individual chain lengths in the alkyl radicals of monomer 1, and j is the serial variable for the individual chain lengths in the alkyl radicals of the amide and/or imide groups of monomer 2.
